Microbiological quality of the water of recreational and rehabilitation pools: a 2-year survey in Naples, Italy.

OBJECTIVES: To analyse and compare the microbiological quality of the water in rehabilitation and recreational swimming pools in Naples, Italy. STUDY DESIGN: A 2-year survey investigated the microbiological quality of the water in seven recreational and rehabilitation pools, and the findings were compared with local guidelines. METHODS: For each facility, water was sampled at the intake point and at two points inside the pool. Total microbial contamination and Pseudomonas aeruginosa contamination were evaluated. RESULTS: Microbial mesophilic contamination and P. aeruginosa contamination were found in all seven pools. Microbial mesophilic contamination was more common in recreational pools (3-4.2% samples were above threshold values), probably due to the greater number of bathers. P. aeruginosa was more common in intake water than water inside the pool [mean values of 19.3 and 22.5 colony-forming units (cfu)/ml in recreational and rehabilitation pools, respectively]. A longer period of contact with chlorine and the dilution process may have led to lower levels of P. aeruginosa in the pool water (range 2-15 cfu/ml). CONCLUSIONS: There is a need to improve disinfection and cleaning procedures, with consideration given to the different uses and daily bather loads of each pool type. There is also a need to monitor water quality and to increase users' knowledge and awareness of the risks.

[Health promotion through physical activity: territorial models and experiences]. / Promuovere la salute attraverso l'attività motoria: modelli ed esperienze territoriali.

Scientific evidences support the preventive role of physical activity in relation to different multifactorial pathologies. Health's promotion through the spreading of lifestyles that encourage movement, does not represent just an action in contrast with "sedentary life" risk-factor, but also a priority for "quality" of life, with relevant economical and social benefits. WHO indicates physical activity as one of the priorities for an effective prevention. Besides, the EU supports the realization and the diffusion of some prevention-programs. Main pilot experiences developed in Italy and other countries are summarized. Attention is focused on the role of the competences and structures involved in an integrated approach based on availability of medical support, social services and local structures, considering recent developments in health prevention and promotion. In Italy and Europe, new opportunities to implement health promotion through physical activity are offered by the development of higher education in movement and sport sciences.

A systematic review evaluating the potential for bias and the methodological quality of meta-analyses in vaccinology.

A systematic review was undertaken to produce an annotated bibliography of meta-analyses in vaccinology and to evaluate their methodological quality. Based on our evaluation using the Oxman and Guyatt index, the methodological quality of the 121 meta-analyses included in this study is not satisfactory. The most frequent limitations include non-comprehensive bibliographic research; bias in the selection of the studies; lack of quality assessment of individual studies; absence of evaluation of heterogeneity among studies and publication bias. The methodological quality significantly increases with the year of publication and with declared financial support, without differences between profit and non-profit support. Meta-analyses with a higher Oxman and Guyatt quality score are more likely to include only randomized trials and to explore appropriately potential sources of heterogeneity. Most of the methodological deficiencies of meta-analyses in vaccinology could be corrected easily, and meta-analysts should improve the methodological quality of their work to maintain their impact on policy decisions.
